What is the difference in terms of bleaching power between thick bleach and ordinary 'thin' bleach ?

Posted 18th Mar
Thick bleach contains a thickening agent which makes it thicker so it clings to lavatory surfaces for instance, but if I wanted to make a 10% solution by weight or volume, how much should I use of thick bleach

it's only a gelling agent so it will be sub 0.5% Alkyl ether or the like, dilute as normal 90% water. Sodium hypochlorite content will be the same.
9 parts water to 1 part bleach

100ccs of thick bleach weighs 265 gms.

This is the classic formula, I think, using thin 5.25% available chlorine bleach

Your bleach doesn't have a density of over 2....it will be 1- 1.1 But the active ingredient is sodium hypochlorite ... its anywhere from 1 to 6% the rest of it is water ... sodium hydroxide is added as a stabilising agent. but you won't know specific quantities is in your specific brand of bleach without lab equipment. you're overthinking it. Unless you're trying to make chloroform in which case I wont be helping anymore

I'm not interested in making anything other than !0% solution from thick bleach thanks

Then 90% water is what you need. unless you have a spare mass spectrometer...

Ok, to 10% thick bleach by weight or by volume? It's easier to weigh thick bleach.
Obviously I don't want to use too much bleach or too little.

volume will be the most accurate for you

I am talking about thick bleach, the density of normal (regular?) bleach is I think 1.17

if you're bored and want to do it by weight, use a density of 1.1 for the bleach 9.0909*g of bleach per 900g of water

But this is total overthinking it territoty

Actually it's my mistake, I have a 100ml meauring cylinder but I also have a 250ml measuring cylinder. I was using the latter.
Oh dear

so your density is 1.059 .. on provision that you measure is lab accurate

Apparently, however my scale indicates only to grams. I had one a long time which indicated to 0.00 gms which cost at the time over £1200 IRC, but it died.
Also there were small bubbles in the bleach. I couldn't wait for them to rise (thus lowering the apparent density)

Please put us out our misery. What normal activity will need such a stringent measure of bleach. I’d think that 8-12% in most use cases will be more than adequate. Erring only the side of stronger depending on the application.

10% will do I think
The important point here is, I think to wait 5 minutes
Well I came across it through this

On a final point, is this concentration likely to dissolve a plastic container?

In that case, unless it’s a good surface or an area you have regular skin contact with 10-12% would be fine.
As you say, letting it dwell first is more important.

No, but I want to keep the dilute solution in other plastic containers. I put some in a polystyrene container and after a day it seemed a bit cloudy

This gives 100 ppm what is required is 5000 ppm available Chlorine

You shouldn't really store it as it degrades quickly once you've diluted it. The cloudiness is probably the salts falling out of solution. You ought to make and use as needed.

Ok, well that seems to happen here over several hours. would it last longer if real distilled water was used.?
It's a bit impractical to make when it's needed.

No, it will still degrade. you should get 18-24 hours out of a mix. You'd have to add caustic to stabilise but that would alter your PH which inturn negates the bleaching effect of the sodium

Thanks, It's not very practical then. However useful in an emergency.
What is a simple thing to neutralise it, other than water?
The remainder can be used for mopping up, I suppose.
Water will only dilute it until it decomposes. if you want to netralise bleach Hydrogen peroxide will do it. how much are you making??

what do you want to use it for? how do you want to use it? It sounds like you want to use it for mass deep cleans or something?

Not that much only one litre or less.Just to clean up after people and myself have come into a house and unavoidable touched things before getting to the soap and water. Contamination remains active and/or dormant for almost any time from hours to many days, depending on what it falls on and what misinformation you have read.
